C515 KS-RW

Kennedy Valve revolutionized the gate valve market in the early 1980’s by offering the first resilient seated gate valve in the USA. Today Kennedy is still the industry leader in UL-FM gate valve design and performance up to 24”. All 14”-54” Resilient Seated Gate Valves comply with AWWA C515. Kennedy Valve uses a fusion bonded epoxy coating on all RWGV.

The Kennedy Model KS-RW Resilient Seated Gate Valve embodies all the latest valve technology for simplicity, durability, and superior performance with no compromise in materials or workmanship.

RESILIENT WEDGE GATE VALVE with CLEANTRACK

TECHNOLOGY In America today, systems are increasing their demand for larger-sized water lines. With these growing demands, Kennedy has made the commitment to meet and surpass previous large resilient seated gate valve requirements with a new concept- CleanTrack Technology.

Sediment buildup in valves has been a costly problem since the first water valves were created. In years past, systems with sediment-laden valves faced time consuming and costly valve removal or repair. Advanced large double disc technologies of decades past used various methods to clear the line of debris prior to closing.

Kennedy’s 30”-54” gate valves have taken the best of the century-old double disc design and integrated it with the best of the latest resilient seated gate valve design and technology, to create valves with CleanTrack technology. CleanTrack uses a unique roller-scraper system that automatically cleans the track in the valve body when the valve is closing. Less sediment buildup makes for improved performance which means reduced maintenance and lower potential replacement costs.

THRUST BEARINGS Plastic thrust bearings above and below the thrust collar reduce friction and minimize operating torques.

EPOXY COATING Corrosion resistant fusion-bonded epoxy coating, conforming to AWWA C550 and NSF 61 Certified, protects both inside and outside of valve.

NO FLAT GASKETS O-ring seals at stuffing box and bonnet to body flanges ensures the best possible seal. There are no flat gaskets.
